ARTHUR G. NUTTING, OF ST. PAUL, MINNESOTA, ASSIGNOR T0 CHICAGO PNEUMATICTOOL 00., OF CHICAGO, ILLINOIS.

SAFETY DEVICE.

To all whom it may concern Be it known that I, ARTHUR G. NUTTING, acitizen of the United. States, residing at St. Paul, in the county ofRamsey and State of Minnesota, have invented a certain new and usefulImprovement in Safety Devices, of which the following is a full, clear,concise, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.

My invention relates to safety devices and more particularly concernsitself with safety devices for cars or vehicles.

More particularly my invention is designed to provide certain deviceswhich are available when a car jumps the track, and which devices thenpermit sliding of the car upon the rails, thereby to avoid injury to thecar. Without the safety devices the car may bump over the ties or mayleave the right of way entirely and run into some obstruction.

In the preferred form of my invention, I provide shoes which are soarranged upon the car that when the car jumps the track its shoes engagethe track so as to permit the car to slide on the track and at the sametime provide flanges or other suitable means to guide the car along thetrack.

I have found my invention of particular utility when it is applied tohand cars and the application of the invention has been particularlytested in connection with self propelled inspection cars for railroadsof the three wheel variety. The invention here in is described inconnection with a car of such a character. I find that a car of thischaracter, if it jumps the track, usually jumps to that side of thetrack upon which the single wheel is located and the invention asapplied to such a car herein is shown as providing the necessarysafeguards to. prevent injury to a car of this particular char acter.

It will of course be understood that the invention is not to be limitedin its application to this specific kind of a car as the invention maybe applied to other vehicles and other modifications may be made withinthe scope of my invention. I will however describe this specific form ofmy invention in connection with the accompanying drawing illustratingthe same, in which:

Figure 1 is a side view of a car showing my improved safety device; Fig.2 is a Specification of Letters Patent.

Application filed December 29, 1911.

Patented Jan. 21, 1913.

Serial No. 668,508.

front view of the said car; Fig. 3 is a detail view of one of the safetydevices; Fig. 1 is a detail view of the cooperating safety devices; andFig. 5 is a section of the slide portion of the shoe.

The car to which my invention is shown as being applied consists of aniron framework using as a basis therefor a channel iron 1 to whichsuitable uprights 2, 2 and 3 are attached, which uprights permanentlyhold the platform 4. The car has upon one side wheels 5, 6 and upon theother side the wheel 7. The car is suitably driven by means of theexplosive engine 8. The car is adapted to operate upon rails 9, 10 inthe ordinary manner. Now it frequently happens that a car of thischaracter jumps the rails and this particular form of car when jumpingthe rails frequently jumps in the direction toward the wheel 7. Afterjumping the rail the car may be liable to serious injury either inbumping over the ties or in hitting some obstruction.

My invention is designed to obviate the danger resulting from jumping ofthe track by providing suitable auxiliary means through the agency ofwhich the car may be still confined to the rails after the wheels haveleft the same so that the car may slide along these rails without injuryto the car or road bed. I might add that the devices have been. found toperform their function properly even though the car jumps the track whengoing at a speed of twenty miles an hour.

These safety devices consist on one side i of the car preferably in theform of shoes 11,

11, which shoes have the sliding surface 12 and the flange 13. The shoesare also provided with upwardly extending brackets 14 and 15 by means ofwhich the shoe is held in place on the channel irons 2, 2 through theagency of the bolts 16 and 17. It will thus be seen that the entire shoe11 may be made of one piece for this particular character ofconstruction. On the opposite side of the car, as this car need beequipped only to guard against jumping toward one side, I do not finditnecessary to provide a flanged foot, but provide merely a horizontallyarranged sliding shoe 18 having the shoe portion 19 and two verticallyextending members 20, 20 which are respectively associated with thechannel iron 1 by means of the bolts 21 and 22 respectively.

Now in the operation of the device if we refer more particularly to Fig.2, we may assume that the car jumps from the rails 9 and 10 in thedirection toward the wheel 7. Now when the car thus jumps the rails, theshoes 11, 11 may engage the rail 10 and the shoe 18 comes down on top ofthe rail 9, and the impetus of the car carries the car along the railsas the shoes 11, 11 and 18 slide over the rails. The car is thusprevented from bumping over the ties or leaving the road bed, and afterthe same has been suitably brought to a stop may be re stored to therailswithout any serious in jury having been done.

\Vhile I have herein shown and particularly described one particularform of my invention, I do not mean to limit myself to such specificdescription and illustration, but having thus described one form ofcarrying out my invention what I claim as new and desire to secure byLetters Patent is:

1. In combination witha wheeled vehicle adapted for operation uponrails, said ve hicle having a framework, of a plurality of flangedsliding shoes attached to said framework adapted to, engage the railswhen the wheels leave the said rails, and a flat flangeless sliding shoefor the other side of said vehicle.

2. In combination with a wheeled vehicle adapted for operation uponrails, said vehicle having a framework, of a plurality. of flangedsliding shoes attached to said framework adapted to engage the railswhen the wheels leave the said rails, said flanged shoes being mountedto the side of certain wheels of said vehicle, and a flatflangelesssliding shoe for the other side of said vehicle.

3. I11 a wheeled vehicle adapted for operating upon rails, thecombination with a substantially rectangular framework, of means formounting wheels to said framework, vertical members attached to said.framework, and a flanged sliding shoe attached to said vertical members,sidewardly of the wheels, said shoe consisting of a shoe portion havingupwardly extending mounting ends, said vertical members extendingbetween the converging ends of said shoe.

In a wheeled vehicle adapted for operating upon rails, the combinationwith a substantially rectangular framework, of means for mounting wheelsto said framework, vertical members attached to said framework, aflanged sliding shoe attached to said vertical members, sidewardly ofthe wheels, said shoe consisting of a shoe portion having upwardlyextending mounting ends, said vertical members extending between theconverging ends of said shoe, and means for securing the upperextremities of said shoe and said vertical member together. 7

fivIn af'wheeled vehicle adapted for operating upon rails, thecombination with a substantially rectangular framework, of means formounting wheels to said framework, vertical members attached to saidframework, a flanged sliding shoe attached to said verticalmembers,sidewardly of the wheels, said shoe consisting of a shoe portion h avingupwardly extending mounting ends, said vertical members extendingbetween the converging ends of said shoe, means for securing the upperextremities of said shoe and said vertical member together, and meansfor securing the lower extremity of said vertical member and the lowerextremity of one arm of said shoe together.

6. In a wheeled vehicle adapted for operating upon rails, thecombination with a substantially rectangular framework, of means formounting wheels to said frame work, vertical members attached to. saidframework, and a flanged sliding shoe atcached to said vertical members,said shoe having a shoe portion, and upwardly extending arms, saidvertical members extending along one arm of said shoe.

7. In a wheeled vehicle adapted for operating upon rails, thecombination with a substantially rectangular framework, of means formounting wheels to said framework, vertical members attached to saidframework, a flanged sliding shoe attached a to said vertical members,said shoe having a shoe portion,'and upwardly extending arms, said:vertical members extending along one arm of said shoe, and'meansforsecuring the upper extremities of said shoe and said vertical membertogether.
